On Monday 9th May Sally from Monash University came and taught 3/4D how the digestive system works.
Check out Cate and Samson’s recount of our incursion:
I used to wonder about how we swallow food but when we had such a fun time going to the hall my class and I found out how we digest in such a fun way!
When we walked into the hall we were greeted by an enthusiastic scientist who worked at Monash university who was here to teach us about the digestive system, her name was Sally!
The first thing Sally did with us was telling us how we get our energy the answer to that was food! After that she got my class and I to eat a delicious lolly. While we were eating and swallowing she told us a few facts.
After we had swallowed such a yummy treat! We were taught about the peristalsis then we did a fun activity involving tights and a ping pong ball, it sounds like such an odd mix but those two things together made such a fun game.
Then she got us to get into pairs and head to a table, we had to put a piece of bread in a plastic bag with some water then we had to squish it! This explained how the stomach churned and squished food.
We worked on that activity for a while then at the end we had a choice to touch an ox’s tongue and (or) a pig’s intestine and (or) a pig’s stomach!Knowing that I was squeamish I decided not to touch any of these things!
It was easy to say that this incursion was by far the most interesting incursion I have had so far!
I hope we get to do this activity again because I can certainly say it was fantastic!
When we got there Sally was talking about the Mouth, Teeth and Saliva. She was also talking about sugar and how it digests in your mouth. Then we put a lolly in our mouth and she wanted us to feel the sugar digesting in our mouths. The lolly was delicious.
Then she was talking about the oesophagus. The oesophagus is in your throat and that breaks down the food that we eat. We had to play this game called peristalsis and we had a stocking and a ping pong ball. We got into groups of 5 and we had to push the ping pong ball through the stocking like you ate something and it’s going through your throat. Whichever team won got another lolly and all teams wanted the prize but only one team could win the prize. That team wasn’t my team unfortunately.
After that we did an experiment and we had to put a piece of bread in plastic bag and mix it with water. It looked gross! Then we put cocoa and oats in the plastic bag. Then we put the stuff in a cloth and I had to squeeze the water out. Once all the water was squeezed out of the cloth there was stuff left that was the waste. After we did that we got to touch an ox’s tongue, a pig’s small intestine and a pig’s stomach. We obviously touched those organs with gloves. Straight away I washed my hands. Over all I think it was an awesome, interesting incursion.
